What is an Exoskeleton?
An exoskeleton is an external framework or shell that supports and protects the body of an animal. It is made of a hard material, such as bone or chitin, and is composed of plates or segments that are connected by joints. Exoskeletons provide protection from predators, support for the body, and attachment points for muscles.
Animals that have exoskeletons include insects, spiders, crustaceans, and some mollusks. The exoskeleton of an insect is made of a lightweight and durable protein called chitin. The exoskeleton of a spider is made of a tough and flexible material called silk. The exoskeleton of a crustacean is made of a hard and calcified material called calcium carbonate.
Exoskeletons are an important part of the anatomy of these animals. They provide protection, support, and attachment points for muscles. Without an exoskeleton, these animals would not be able to survive.
